DEVICE FOR CARRYING AND SUPPORTING MAPS, 80C.

SPECIFICATION forming part of Letters Patent No. 733,137, dated July '7,1903.

Application filed September 22, 1902. Serial No. 124,380. (No modclJmeans for the carrying and supporting of maps, curtains, pictures, andother flexible sheets in such a manner as to render themeasilyaccessible and at the same time to keep them in an extended form, sothat they will not become rumpled, creased, or broken, and at the sametime to permit of their being rolled upon themselves, so as to preservethem from the action of light and dust and also for the purpose ofoccupying lessspace.

This device is designed to be suspended from or attached to a wall orlaid flat or attached to a desk, table, or other appropriate surface, sothat the articles carried by it may be unrolled therefrom in eitherapendent or horizontal manner.

The purposes of this device are as follows: first, to show by mechanicalmeans either and both sides of such maps, pictures, and other flexiblesheet as shall be printed, painted, sketched, or drawn on each and bothsides of said flexible sheet while suspended on a wall or otherperpendicular support; second, to preclude the necessity of turning ortwisting a map or other flexible sheet from one side to the other forthe purpose of seeing the reverse side; third, to enable said maps orother flexible sheet to be changed frequently with little effort and bymechanical means in order to expose either side thereof to view withoutthe liability of rumpling, cracking, or unduly creasing or defacing thesurfaces of said flexible sheet.

This device consists of two parallel rollers of equal or different sizeaxially supported at both ends of both rollers, so as to be equallydistant from each other throughout their whole length, said axialsupport to be in turn revolubly supported at or near its center ofgravity, so that both of the parallel rollers are free to revolve upontheir own axis and also to be revolved one over the other in a planetarymanner, all as hereinafter described, and pointed out by the claims,reference being had to the annexed drawings, forming part of thisspecification, and in which like symbols represent corresponding parts,and wherein- Figure 1 is a perspective view showing a map or otherflexible sheet pendently suspended from a vertical surface. Fig. 2 is ahorizontal view of one end of each of two parallel rollers axiallyentered into a revoluble plate having a trunnion on the side opposite tothe rollers and at or near its center of gravity. Fig. 3 is an end viewof the two parallel rollers and the revoluble carrier suetaining them.Fig. 4 is a side and Fig. 5 is a front view of a supporting-bracket intowhich the revoluble carrier is rotatively entered. Fig. 6 isa plan View,and Fig. 7 is a side view, of the revoluble carrier.

A is a map, curtain, or other flexible sheet.

13 and B are two cylindrical rollers provided with trunnion-shaped axlesb and b on the outer ends thereof.

C is an oblong or elliptical carrier provided with two holes 0 and defproper size to easily admit the trunnions b and b on the ends of therollers B and B and at such a distance from'each other as to allow ofthe introduction of a map or other flexible sheet between the peripheryof the two rollers when they are axially entered into the revolublecarrier C.

D is a support or bracket provided with a hole 61 in the outward orupward projecting part thereof of sufficient size to easily admit thetrunnion 0 which is integral with or fixedly fastened into a revolublecarrier C and on the opposite side from which the rollers B and B areentered into said carrier. The opposite end of this support or bracket Dis formed into a foot and provided with hole d, by which it may bereadily attached to any perpendicular or horizontal surface with ordinary bolts or screws.

The operation of this device is as follows, reference being had to Fig.1: On exerting traction upon one end a of the map A it is evident thisend of the map will pass down between the horizontal rollers 13 and B,and

the surface a will be the outward surface and exposed to view, while byexerting traction on the opposite end a of the map A this end of the mapwill pass down over one of the rollers, as B, and the surface a will bethe outside surface and exposed to view. It now the two rollers B and Bbe caused to rotate planetary fashion about each other around the axison the carrier 0, it will cause the map A to be wrapped around both ofthe rollers B and B until it is entirely'rolled up about them anditself.

It is obvious that the map A is provided with sticks or other means ofenlargement at its extreme top and bottom edges to prevent the map frompassing entirely between and out of contact with the rollers B and B. v

Having'fully described and explained the merits of this device, what Idesire to claim and secure by Letters Patent is as follows:

1. In a device for the carrying and supporting of maps, curtains, &c., aplurality of supports, a plurality of revoluble carriers journaled insaid supports, a plurality of rollers journaled in said carriers, aflexible sheet supported between said rollers and adapted to besustained at any part of its length by the pressure of said rollers uponthe sheet, substantially as specified.

2. In a device for the carrying and supporting of maps, curtains, &c. aplurality of revoluble carriers, a plurality of rollers journaled insaid carriers, a flexible sheet supported between said rollers, havingeach end of said sheet free from said rollers and adapted to be drawnaway from said rollers, substantially as specified.
